pmichaud what/where are the instructions for building nom? 15:01

pmichaud with --gen-parrot? 15:06
that seems... unlikely.

colomon pmichaud: rakudo nom or nqp nom? 15:06
for rakudo nom, you need --gen-nqp as well 15:07

pmichaud colomon: rakudo nom. (There shouldn't be a nqp-nom)
15:07 baest_ joined
colomon Then unless you have that nqp built, definitely --gen-parrot --gen-nqp 15:07
pmichaud so, both --gen-nqp and --gen-parrot ?
colomon yes
pmichaud okay 15:08
we should eliminate the --gen-parrot option
colomon (I also needed the --without-pcre option for --gen-parrot)
pmichaud I think jnthn++ and I had discussed that eventually we should just build from nqp, and let nqp handle the parrot revision
I'll start moving things in that direction. 15:09

pmichaud nqp seems to be tied to Parrot 3.3.0.... should we bump that? 15:12
moritz +1 15:13
pmichaud especially since 3.4.0 is quite a bit faster than 3.3.0
oh, and nom appears to be using parrot with the GMS gc 15:14
so that makes it EVEN SLOWER
s/nom/nqp/
wait, rephrase
nqp appears to be using parrot with the ms2 gc 15:15
with the bad tuning... so it's about 60% slower than it ought to be (based on Rakudo benchmarks)
does Rakudo-nom still need any of its own pmcs or ops? 15:17

slower than it was in January 2011. Moving to Parrot 3.4.0 uses the GMS gc, which gives a huge overall performance speedup and an even bigger speedup for regexes and parsing.		 15:24

pmichaud please speak up soon if you feel that rakudo should be based on a parrot revision instead of an nqp revision. 17:04
17:04 ab5tract left
pmichaud my plan is to eliminate PARROT_REVISION from nom, and simply have NQP_REVISION 17:05
the version of NQP will then decide what parrot is wanted/required
mberends +1
17:05 cdarroch joined, cdarroch left, cdarroch joined
benabik If rakudo will still have custom ops and/or pmcs, then keeping a PARROT_REVISION might be wise. 17:05
pmichaud I'm expecting those to go away.
(I might be wrong there... but that's my expectation.) 17:06
benabik Well then +1 to making them go away and +1 to NQP_REVISION :-D
pmichaud even if they don't go away, I think it'll be easy-ish to bump parrot revision in nqp 17:07
benabik Commits in NQP saying "bump PARROT_REVISION so Rakudo can ___ 17:08
" seems odd to me, but I'll admit I'm the peanut gallery here.
pmichaud I think parrot downloading and revision management should be in one place, not two. 17:09
benabik Bad idea: Have Rakudo's Configure.pl overwrite NQP's PARROT_REVISION if needed.
pmichaud not going there. :) 17:10
17:10 zorgnax left
pmichaud in general, I think that NQP should be our "interface layer" between Rakudo and Parrot, rather than having Rakudo target Parrot directly 17:10
especially since we want Rakudo to become less parrot-centric. 17:11
that's obviously something we'll violate when performance demands
but the number of violations ought to be small enough that Rakudo isn't driving the PARROT_REVISION bus
benabik pmichaud: Sounds sound. 17:12

PerlJam why is nqp:: a pseudo package? 17:50
17:50 mberends left
PerlJam (I mean it doesn't have to be right?) 17:50
pmichaud things in the nqp namespace are handled specially by the compiler, atm.
as opposed to being standard namespace lookups
moritz PerlJam: syntactically it looks like a package
PerlJam: which is why we call it "pseudo package" :-) 17:51
pmichaud is there a better (more canonical) name for the "build/" subdirectory?
PerlJam pmichaud: right, so does that mean that the way to handle nqp:: is to use the normal mechanism?
pmichaud PerlJam: I don't quite understand the question. 17:52
moritz we don't want nqp::join to compile to a package lookup + invocation
but rather to a more low-level thing
pmichaud nqp:: becomes the interface to the underlying vm

pmichaud well, so far these are developer-facing changes, not user-facing ones.
tadzik oh well
colomon ./perl6 => ./rakudo +1 18:21
PerlJam er ... why? 18:22
18:31 mberends joined
tadzik for there's no One Perl 6 Compiler. Why should 'perl6' be reserved for Rakudo, and not for Yapsi? :) 18:38
PerlJam who said it was reserved? 18:39
tadzik well, it's not 18:40
PerlJam maybe someone should circumvent the problem by creating perl6brew now ;-)
colomon especially considering that people will probably want to run rakudo master (soon to be known as beta?) and rakudo nom side-by-side for the next three months or so... 18:41
colomon 's computer has mysteriously started playing some excellent Irish polkas... I think I know what they are, but have no idea why they are playing nor in what window. 18:42
PerlJam colomon: What if there were an option --install-as=whatever ?
tadzik hmm
rakudo: sub marine
p6eval rakudo 369665: OUTPUT«Could not find sub &marine␤ in main program body at line 22:/tmp/sRNhSA8Yft␤»
tadzik :) 18:43
colomon PerlJam: that would be nice, for sure. 18:47
18:48 MayDaniel left
tadzik rising up a question again. I need to be able to somehow set up a global-ish variable in Actions.pm, and frequently append information to it. How do I do that? Is there anything in Rakudo currently which I can look at for inspiration? 18:48
18:50 wamba left
PerlJam tadzik: you mean like @BLOCK ? 18:50
tadzik hmm, maybe our @FOO; and some set_hll_global magic?
PerlJam: it needs to be available in runtime.
see $=POD, but for now whatever works
PerlJam oh
for a second there I had no clue what you were working on :) 18:51
tadzik or something like PAST::Var.new( :name('self'), :scope('global') 18:52
18:54 Mowah_ left
tadzik pokes moritz 18:55
PerlJam tadzik: :scope('package') wouldn't work? 18:56
that seems like what you'd want anyway
pmichaud even just our @FOO and repeated pushes would work
tadzik pmichaud: it will be available in runtime then?
Or would I need some set_hll_global for that? 18:57
pmichaud if you look in the right package, yes.
moritz tadzik: pong
tadzik PerlJam: in an ideal world it should be file-scoped. But as I say, the proper way is for week 10th or something, it turned out I need something for testing now
pmichaud as a first attempt, you could try "our @FOO" and then look in @Perl6::Actions::FOO
tadzik moritz: following?
moritz tadzik: just backlogging.. 18:58
pmichaud you can also do something like our @FOO := @Some::Other::Package::FOO
moritz tadzik: define a global variable in the same way that $*PERL etc. are defined
pmichaud which binds @FOO in the local package to a @FOO in Some::Other::Package 18:59
moritz tadzik: and then emit calls @FOO.push($things)
tadzik moritz: $*PERL is in cheats/somewhere.pm
moritz sorry, afk
pmichaud note that all of this will work only if "runtime" means "same process where the Perl 6 code was parsed" 19:00
if a file gets output to .pir, the $=POD won't be serialized with it (but that sounds like week 10th or something to me)
tadzik yeah. For now it's just "whatever lets me test the parser in more-less complete way"
also, I'll need to have Pod6 nodes in Nqp, not Perl6, right? 19:01
not much loss though
pmichaud not sure about that.
and I still expect to want/need to serialize a copy of the source code in the compiled output anyway, so POD thingies could make reference to that. 19:02
tadzik afk for a longer while. Thanks for the tips
19:10 fhelmberger left 19:18 birdwindupbird joined 19:23 keeth left
jnthn pmichaud, tadzik: When we have the proper serialization stuff in place, then we can just build the POD data structures during the compile and shove 'em in the SC. 19:23
jnthn doing family stuff, mostly afk :) 19:26

where do I define classes so I can use them in Actions.pm? 20:44
20:45 tomaw_ left 20:47 ymasory joined, silug left
moritz tadzik: src/Perl6/*.pm has some examples 20:55
tadzik: though most often you don't need to use them in Actions.pm directly, but rather emit calls that construct them
tadzik so they will end up built at runtime?
moritz aye 20:56
20:56 tomaw_ joined
moritz at least that's the current approach 20:56
will change with nom
tadzik problems so far: nopaste.snit.ch/47776 20:57
moritz doesn't feel really qualified or concentrated right now
tadzik ok, no hurry
moritz btw, our @POD := []; should work just as fine 20:58
20:59 mtk left
tadzik moritz: so in the current approach Pod6::Nodes will become a part of the settings library? 21:00
moritz tadzik: yes
tadzik moritz: @POD := [] later results in NPA on find_method('push') 21:01
21:01 rokoteko left
moritz urks. 21:01
21:03 tomaw_ is now known as tomaw 21:10 mtk joined 21:13 Bucciarati left, bluescreen10 left 21:20 ymasory left
tadzik pushing "quick and dirty" to a whole, new level: nopaste.snit.ch/47777 21:20
21:21 Bucciarati joined
tadzik guess it's sleepytime, once I started coming out with things like this 21:21
moritz tadzik: you can try my @POD = infix:<,>(@Perl6::Actions::POD)
iirc that was the way to turn a RPA into a Perl 6 array
moritz -> also sleep 21:22
lichtkind moritz: good night
tadzik moritz: neat!
moritz: sleep tight
21:23 Zapelius left
lichtkind im shoot at anyone calling be zebra or panda :) 21:23
